Contact Assembly For Uniform Pressure Distribution In Circuit Breakers

Abstract: The present invention relates to a contact assembly for circuit breaker. The assembly comprises plurality of contact means including fixed and moving contact means (1), shaft means (6) operatively connected to moving contact means (1) so as to co-operate with the movement of the shaft (6), holding means (3) with its one end connected-to moving contact (1) so as to provide suitable movement of the moving contact (1) about an appropriate axis and the other end suitably linked to the shaft means (6). The supporting elements (10) adapted to support holding means (3) and providing desired movement of the moving contact means (1) and actuating means (5) operatively connected, to said shaft means, (6) at one end and to holding means (3) on other end delivering appropriate amount of force to the holding means (3) thereby causing movement of the moving contact means (1) whereby the moving contact means (1) rotatably moves in a manner to provide current continuity, and uniform pressure distribution between the fixed and the moving contact means.
